(I am so glad that things have changed. In 1963, when I was labeled a "gifted student" things were not great. I took part in one of the first studies on this. Half the chosen went to live in dorms at university at 15, the rest stayed in local schools with added support. Guess which cohort succeeded? Yep not mine. University at 15 fucked me up.)
